hi guys been asked to clean these cream colured patio umbrellas. they are green on the top of them with algae. i was just going to pre spray them with non caustic tfr then use a waterfed pole to rinse / brush off. the tfr wont damage the material will it? i should not think it will be a problem.

hi drive surgeon     i have tried different ways to wash these things
                             the best results i have had has been when they are wet with rain water (soft-
                             water)   rinse over with a solution of ariel actilift   allow to dwell  then wash of
                             with a light wieght fsc    on very low pressure/flow rate &&&&&&&&&&&&&&&
                             be very carefull with the seams/stitching
                             or tell the custy to buy a green one next time

A broom is best

thanks jaespray. i have just bought some actilift gel. will mix it with some water and pump sray it on , leave to dwell for 20 mins then waterfed pole/ brush it off.

hi drive surgeon     i would not use a sprayer  the pump action will make foam to much   the ariel actilift i use is the powder one   and apply with bucket/broom

Do not use tfr it can cause permanent damage and ruin the waterproofing we use SWIFT & SURE safe algae remover just spray on and leave it the algae will be eradicated,only badly effected material will need brushing off.
